A Note on Security of Knapsack Type PKC with Random Sequence

Abstract (in Japanese) (See Japanese page) 
(in English) Present author proposed a new method for constructing knapsack PKC
by using a random sequence.
In this paper, we propose two concrete knapsack schemes
whose public key is almost indistinguishable from a random sequence.
We show that the proposed schemes can be secure against the low-density attack
because the density can be made as large as one desires.
We also discuss the security of the secret key of the proposed schemes.
